As with previous NOP this is a version of Puppy Linux WITHOUT abiword and gnumeric office apps. The idea being that you install to a flash drive (or frugal install on your hard drive) and add the open office sfs package (or a 'goffice' sfs pack to restore abiword etc).

NOP 4.0 is based on Puppy 4.0 "Dingo" and uses the xfce4.4.2 desktop with jwm and rox removed along with games and other non essential apps to produce an iso of around 80 Mb.
Seamonkey webbrowser is replaced with Opera and gxine is replaced by xine-ui. Opera is also a good e-mail client and so replaces sylpheed too!

Update:
OK I am posting from Dingo NOP
Is it good. Yes. It uses the elegant Xfce interface
but it lacks Geany (it has mouspad text editor) and Mtpaint - I kinda rely on those . . .
What it does have of course is the Dingo base, Opera browser
and is therefore an excellent base to add Gimp or Inkscape
OpenOffice, Firefox etc.
The layout is different to Puppys but very clear and clean.
A lot of people will be very happy with Dingo NOP

Couple of supplementaries. Yes, this should be on Derivatives.
Can you afford the luxury of both analogue and digital clocks? This version is smooth and fast. The target is still size-reduction?! Xfce is always worthwhile.

And a few more. The help message obscures the top menu bar initially with the liveCD. Not sure whether you are using the latest installer? The GRUB installer is the older version in which the CD tray loops-the-loop, but I don't think the latest one does that any more?Edited_times_total

The only solution I can see is the formation of a group named "critical mass". Even if it contains no one but you, AJ, I think it would rate as "super-critical", possibly even explosive. If we get a good response, ("chain reaction",) I will nominate you as official "initiator", playing the role of "tamper" or "reflector" myself. (There's just one question in my mind: are you capable of emitting anything neutral, i.e. uncharged? You strike me as a high-energy alpha emitter. If so, we may need to surround you with an inner circle called "Beryllium". )

With an admitted alien in the "core" group, we could attract testers from DHS and the NRC, though it would be open to the IAEC. They are probably reading this post already!

Could I suggest that you create a thread in the 'derivatives' section as the main one for discussion / questions etc.

I always thought it was a pity that the NOP3.01 'discussion' thread ended up in announcements only from the point of view of new people trying NOP when they decide to look for a derrivative but miss all the info about NOP since it is in the announcements thread.

Sage: The analogue clock looked so good I just had to have it. The size is minimal as I have used MU's Gtkbasic to replace puppy basic (it is puppybasic with gtk call extensions) and it is not much bigger. The basic script for the clock itself is only 10K !
This looks a very interesting programming tool that I plan to investigate and gives the ability to do widgets/desklets etc without the bloat. If you dont like it you can switch it off using the system, autostarted applications menu option. I wanted to keep NOP fairly minimal but have kept xsane / sane / gtkam / fotox for now. If I remove these apps I could knock another 4mb off the iso size - opinions on this would be appreciated.
The help bar and Grub issues are from the standard Dingo, untouched.

AJ: Much of NOP is still DIngo & so same bugs will be found !!

Dingo seems pretty solid - it has been out over a week now with very few problems reported.
